FGL            Fine Grained Label [RFC7172]
FS-LSP         Flooding Scoped Link State PDU [RFC7356]
PDU             Protocol Data Unit

corrections

1.   page 5 section 3.2 - first paragraph - first sentence
[Both L1 and L2 are areas so "each L1 area and L2" reads a bit weird.]
(as written)
Distribution trees for flooding of multi-destination packets are 
calculated separately within each L1 area and L2.
(I'd write)
Distribution trees for flooding of multi-destination packets are 
calculated separately within each L1 and L2 area.

2.   page 9 second paragraph - first sentence
["packet is originated" is weird wording. I don't think "is" is needed.]
(as written)
if this packet is originated from an area out of the connected areas, 
RB1 should replicate this packet and flood it on the proper Level 1 
trees of all the areas in which it acts as the DBRB.
(I'd write)

RB1 should replicate this packet and flood it on the proper Level 1 
trees of all the areas in which it acts as the DBRB.

3.   page nine third paragraph - first sentence
["packet is originated" is weird wording. I don't think "is" is needed.]
(as written)
if the packet is originated from one of the connected areas, RB1 
should replicate the packet it receives from the Level 1 tree and 
flood it on other proper Level 1 trees of all the areas in which it 
acts as the DBRB except the originating area (i.e., the area 
connected to the incoming interface).
(I'd write)

on other proper Level 1 trees of all the areas in which it acts as 
the DBRB except the originating area (i.e., the area connected to the 
incoming interface).


4.   page 9 fourth paragraph - third sentence
["can well appear" would read smoother as "can appear"]
(as written)
RBridges that do not support either E-L1FS or E-L2FS cannot serve as 
area border RBridges but they can well appear in an L1 area acting as 
non-area-border RBridges.
(I'd write)
RBridges that do not support either E-L1FS or E-L2FS cannot serve as 
area border RBridges but they can appear in an L1 area acting as 
non-area-border RBridges.

5.   page 11 second paragraph - third sentence
["will finally flooded" should be "will finally be flooded"]
(as written)
This packet will finally flooded to RB77 via RB30.
(should be)
This packet will finally be flooded to RB77 via RB30.
